Privacy Policy

1. Who We Are

base64encodetool.com is a free, developer-focused utility for encoding and decoding Base64 strings. The tool is operated as an independent micro-SaaS project. For privacy-related questions, you can contact us at the address provided in the Contact Us page.

2. What Data We Collect

We collect the absolute minimum necessary to operate the website:

• No input data. The text you type into the encoder or decoder is processed exclusively in your browser. It is never sent to any server, never logged, and never stored anywhere outside your own device.
• No account data. We do not offer user accounts. There is nothing to sign up for.
• No cookies for tracking. We do not set any first-party tracking or analytics cookies.
• Minimal server logs. Like any web server, our hosting provider may record standard access logs (IP address, requested URL, timestamp, HTTP status code). These are retained for a short period for security and infrastructure purposes only and are never sold or shared.
• Theme preference. Your chosen light/dark mode preference is saved in your browser's localStorage — it never leaves your device.

3. How the Tool Works — Technical Explanation

When you visit base64encodetool.com, the browser downloads a small bundle of static HTML, CSS, and JavaScript. From that point on, all encoding and decoding operations are performed by your browser's JavaScript engine, using the built-inbtoa() and atob() APIs (or equivalent TextEncoder logic for full Unicode support). There is no server-side processing step. You can confirm this yourself by opening your browser's DevTools → Network tab and observing that no network requests are made when you type into the tool.

This architecture means that even if our servers were compromised, an attacker would have no access to any data you have encoded or decoded.

4. Third-Party Services

We use a small number of third-party services to deliver the website:

• Hosting / CDN. The site is deployed on a static hosting provider. Their infrastructure handles TLS termination and content delivery. Standard server access logs may be retained by them per their own privacy policy.
• Google Fonts. We load the Inter and JetBrains Mono typefaces from Google Fonts. When your browser fetches these fonts, Google may log your IP address. See Google's Privacy Policy.
• Google AdSense (if applicable). We may display ads served by Google AdSense. Google may use cookies and device identifiers to show personalised advertising. You can opt out viaGoogle Ads Settings. We have no access to any data collected by Google for this purpose.

5. Cookies

We do not set first-party cookies. Your theme preference (light/dark mode) is stored in localStorage, which is local to your device only and is never read by our servers.

Third-party cookies may be set by Google Fonts or Google AdSense as described in Section 4 above.

6. Your Rights

Because we do not collect personal data, most data-subject rights (access, erasure, portability) do not apply in practice. However, if you have a privacy concern, please contact us and we will respond within 30 days.

If you are located in the European Economic Area (EEA) or the UK, you also have the right to lodge a complaint with your local supervisory authority.

7. Children's Privacy

This tool is not directed at children under 13. We do not knowingly collect any information from children. If you believe a child has submitted personal information, please contact us immediately.

8. Changes to This Policy

We may update this Privacy Policy from time to time. We will update the "Last updated" date at the top of this page when we do. Continued use of the tool after changes are posted constitutes acceptance of the revised policy.
